Abstract: A new method and apparatus includes the inspection of structural wooden members within a structure wall, and then the isolation of the wooden members infected with the insects. Heat producing devices are positioned adjacent to a first one of the isolated wooden members on the outside of the wall. The positioned heat producing device is then activated, and the adjacent isolated wooden member is caused to be heated to increase the temperature thereof sufficiently to kill a large number of the insects contained therewithin to eradicate substantially the entire infestation thereof. The heat producing device is then deactivated after the insect killing temperature has been attained. Thereafter, the remaining individual ones of the isolated infected wooden members are treated in a similar manner.

Abstract: This invention concerns a non-toxic method of exterminating dry wood termites, fleas, roaches, ants, weevils and the like by utilizing an inert freezing liquid such as liquid nitrogen as the killing agent. The liquid nitrogen is inserted so as to envelop the colony of objectionable organisms until the environment is reduced to a temperature of at least zero degrees Fahrenheit and maintained at that temperature for between 2 to 5 minutes. This method effectively kills the organisms by crystalizing the innards and freezing the cells, thereby eliminating the need for more dangerous and toxic poisons that are currently being used.
